Editor’s note: This is the second part of a two- part series.
In my last column I covered some of the basics regarding temperature changes and the effects they have on measurement. Fortunately, unlike the climate change folks, we don’t have to worry about our labs being flooded because of an icecap melting or polar bears in the parking lot. But we do have to deal with them.
There are two approaches to take. The first is to control the shop or lab environment to such an extent that, whatever temperature variations remain, they will have no significant effect. The alternative is to control and correct the key items involved-the gages and the product being measured. The simplest method for most folks is to control and correct. Here are some ways to do this:
There are other ways to deal with these problems, but like any problem-solving, first you must determine if you have a problem and its magnitude. Unlike the global warming climate change folks, we can’t blame someone or something else for the apparent problem without hard evidence to back us up. And we can’t count on consensus “science,” international politics or the UN for support.
